I have a Trailers USA. Oversize/warmbloods stalls, side ramp,divider between the straight stalls slides flat against the sidewall to make a box and or drive a cart up the back ramp and into the front (it was made for someone who drove). Door between front & back straight stalls isn't like a regular stock trailer divider but I will (eventually replace the two swinging doors for a single divider to have two box stalls. I have trailered 3 horses in it as-is. Super lightweight, I pull it with a 2005 Silverado 2500, has plenty of room for all my stuff, and is a 2008 but great condition. I heard mixed reviews on USA, but I'm happy with mine.
My Hawk 2+1 makes me happy every single trip. Love it! http://www.happytrailstrailers.com/ is where I got mine. I worked closely with Risa and had a lot of options put in mine like fans, water under the gooseneck, extra windows, ramp with doors in the back and more. She was absolutely excellent to work with and I highly recommend her.
I frequently haul young tb's and having the various options of side loading and loading from the back is great. I love having the box to tack and I can fit four horses in there as well. My box is bigger so I can put two horses side by side up there for short trips. Love my trailer!
Sorry Hanoverianlover, I didn't get back to this post until now. I pull my living quarter 2+1 with a Dodge Dually diesel.
Here's a video made by Shadow of my trailer when it was new on their lot. I just love it. Great trailer. http://www.youtube.com/watch?v=N0BwQ...7&feature=plcp
